High-biomass saccharomyces cerevisiae strain EnhSa-13 as well as breeding method and application thereof

The invention provides a high-biomass saccharomyces cerevisiae strain EnhSa-13 as well as a breeding method and application of the high-biomass saccharomyces cerevisiae strain EnhSa-13. The strain is obtained by taking a saccharomyces cerevisiae strain Sa-10 as an original strain and adopting a mutagenesis screening method of compounding diethyl sulfate and normal-temperature and normal-pressure plasma (ARTP). The strain EnhSa-13 is preserved in the China General Microbiological Culture Collection Center (CGMCC), and the preservation number is CGMCC NO.24946. The strain EnhSa-13 is named as EnhSa-13. Experiments prove that the mutation breeding method of the strain EnhSa-13 provided by the invention is simple, efficient, safe and stable, the biomass of yeast generated by the obtained strain EnhSa-13 is effectively improved compared with that of an original strain, the quality of a yeast culture product of the strain is improved, and the production cost is saved. 本公开提供了一种高生物量酿酒酵母菌株EnhSa-13及其选育方法与应用。该菌株以酿酒酵母菌株S
